Browsers & apps
Firefox 94 released with support for the
enterKeyHint attribute, which now has universal coverage across major browsers, and some groundwork for cascade layers.
Chrome 95 is out, with support for the Eyedropper API (read a write-up by Patrick Brosset and Thomas Steiner) and
URLPattern polyfill is available if you want to start using the feature today.
Safari Technology Previews have been on a roll in recent months. Highlights from Safari TP 134 include the
<dialog> element, support for color spaces in
<canvas> (like in Chrome,
display-p3 are currently available), and cascade layers. On top of that, WebKit is getting a new layer-based SVG engine, developed by Igalia with backing from *checks notes* the makers of the Thermomix multicooker? Neat!
Adobe Photoshop and Illustrator are coming to the browser. A write-up on web.dev describes the technicall nitty-gritty that makes this possible. In the desktop app, Photoshop added perceptual gradient interpolation in the Oklab color space, which is also being added to the CSS Color Level 4 spec.

Patterns and idioms
In HTML Concepts: Common Idioms, Jens Oliver Meiert points to a section in the HTML spec that proposes markup patterns for things that don't have dedicated elements, such as footnotes or breadcrumb navigation.
Let's Talk about Native HTML Tabs, Dave Rupert on
With one HTML, we can solve two birds with one stone. We get an accordion and a tabs control from the same single element. We can actually use one element and have infinite affordances.
Speaking of native, in Having an open dialog, Scott O'Hara revisits the
<dialog> element to see what has changed in the last couple of years:
<dialog> is almost here. [...] But, until the
<dialog> is actually fully delivered, I personally suggest continuing to use trusted and robust custom dialogs.
Evaluating Clever CSS Solutions by Michelle Barker. Designers have always exploited API affordances to their advantage. We're now seeing new idioms, enabled by recent additions to CSS, that are downright cryptic without documentation.

Security and performance
Which SVG technique performs best for way too many icons? by Tyler Sticka explores the best way to include lots of SVGs on a page:
If you want all the features of SVG and your icons are well optimized, inline SVG is your best bet. Simple and performant. If your icons are complex or poorly optimized, or if you don’t need all the bells and whistles of SVG, image elements are the most performant option, especially using data URIs (encoded as escaped XML, not Base64).
Finding and Fixing DOM-based XSS with Static Analysis from Mozilla's Frederik Braun discusses an ESLint plugin that spots unsafe coding practices, such as assigning to
innerHTML without sanitizing, and plans for Firefox to support the native Sanitizer API.
Tom MacWright has been blogging about technical decisions in Placemark, his work-in-progress geospatial data editor.
The State Of The Web by Jeremy Keith.
There’s a great German word, ‘Verschlimmbessern’: the act of making something worse in the attempt to make it better. Perhaps we verschlimmbessert the web.
The Greatest CSS Tricks Vol. I eBook (PDF and EPUB). Chris Coyier enlisted the help of Baldur Bjarnason to produce an ebook of choice CSS Tricks articles.

CleanUp.pictures, a web app and open-source project that lets you remove objects from images.
It uses LaMa, an open-source model from Samsung’s AI Lab to automatically & acurately redraw the areas that you delete.

CookLang, a lightweight recipe markup language.
Showing GitHub issue titles inline. Simon Willison:
if you paste in a link to an issue or PR in another repo it will display it as a truncated URL, but if you instead add it in a hyphenated bullet point it will display the title of the issue and and indicate if it is open or closed. — very useful!
Math.hypot(). A function I write over and over is the distance between two points. I wasn't aware there's
Math.hypot() to compute just that, so I can write it shorter and clearer:
let distance = Math.sqrt(Math.pow(p2.x - p1.x, 2) + Math.pow(p2.y - p2.y, 2));
let distance = Math.hypot(p2.x - p1.x, p2.y - p1.y);
Fixed-angle gradients in SVG. Did you know the length of the CSS linear gradient depends on the object's width and height? I looked at how to obtain the SVG equivalent in this Observable notebook.
